The intersection shown in FIG. 7 indicates a plane intersection state, and the plane intersection 104 is configured by the first road 100 and the second road 102 intersecting in plane on the ground.
[0004]
The first and second roads 100 and 102 are provided with three lanes of a left turn and a straight lane 106, a straight lane 108, and a right turn lane 110 in order from the left side at the entrance of the plane intersection 104, and a straight lane 112 as an opposite lane. There are a total of 5 lanes with 2 lanes.
[0005]
The traffic route of the vehicle in the plane intersection 104 is in a state indicated by an arrow in the figure, and the traffic of the vehicle is arranged by a signal.
[0006]
The pedestrian crossing 114 is provided over the entire width of the first and second roads 100 and 102 around the plane intersection 104.
[0007]

Japanese Patent Laid-Open No. 54-47333
[Problems to be solved by the invention]
In the structure of the intersection in FIG. 7, vehicles in all lanes of the first and second roads 100 and 102 enter the plane intersection 104, so the signal waiting time becomes longer and traffic congestion occurs. It becomes a bottleneck that is the main cause.
[0013]
In addition, since the pedestrian crossing 114 is provided over the entire width of the first and second roads 100 and 102 around the plane intersection 104, it must cross a five-lane road, and the walking distance is long. In order to go from the predetermined block to the block opposite to the diagonal, it is necessary to wait for the signal twice, which takes time and is inconvenient for the pedestrian.
[0014]
Further, the plane intersection 104 becomes a vehicle-dedicated space where pedestrians cannot enter, resulting in alienation of pedestrians and division of the greening network.
[0015]
In the structure of the intersection shown in FIG. 8, the straight lanes 124 and 126 of the elevated road 118 have no signal and can contribute to traffic congestion mitigation. As in the case of FIG. 7, it becomes a bottleneck that is the cause of traffic congestion.
[0016]
In addition, the walking distance of the pedestrian crossing 114 is long, and there is inconvenience of pedestrians such as waiting for two traffic lights to go to the street opposite to the diagonal. The division or the like occurs as in the case of FIG.

In this manner, the straight lanes 16 and 18 of the first road 10 are the elevated roads 32, and the straight lanes 24 and 26 of the second road 12 are the moat split roads 34, so that no signal is sent to the vehicle straight ahead and the bottle The occurrence of the bottleneck can be eliminated and the traffic jam can be eliminated.
[0054]
Further, it is only necessary to form the right and left turn portions of the vehicle on the ground surface. By making the right and left turn portions into the slow running region 40, the walking space 42 including the slow running region 40 can be formed at the intersection portion 14, and By forming the walking space 42 flat, it is possible to form a pedestrian-preferential barrier-free intersection 14 without a signal.
[0055]
Moreover, since the pedestrian crossings 52 and 54 are not provided over the entire width of the first and second roads 10 and 12, but are designed to cross toward the open space 48, the walking distance can be short, There is no need to wait for a signal twice to go diagonally across the street.
[0056]
Further, the right turn vehicle passage 46 in the intersection is a rotary type, a square space 48 is formed in the center, and trees 58 are planted in the square space 48 and the sidewalk 50 around it, thereby improving greening. It is possible to form an open space that promotes the exchange of people that leads to the activation of the surrounding area.
[0057]
Thereby, for example, in an urban area, the efficiency and amenities of the urban area can be improved and the overall urban environment can be improved.
[0058]
In addition, a vehicle-priority space that does not depend on signals by providing vehicle deceleration means 60 at the vehicle entry section to ensure reliable deceleration, or by installing an intelligent transportation system in the deceleration area 40 to control vehicle speed and prevent collisions.
